Product details
Overview
SN74AUC2G07DBVR from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 1.95-V operation and 3.6-V I/O tolerant interfacing. It delivers ±8-mA sink/source drive at 1.8 V, achieves 2.5 ns max propagation delay, and supports partial-power-down via Ioff. Used in level-shifting and wired-AND bus interfaces in portable low-voltage systems.
For engineers reviewing the SN74AUC2G07DBVR datasheet, SN74AUC2G07DBVR pinout, SN74AUC2G07DBVR application, or SN74AUC2G07DBVR equivalent, key selection criteria include open-drain logic compatibility, sub-2-V supply operation, Ioff-enabled power sequencing, and SOT-23 (DBV) package footprint constraints.
Technical Context
This device implements two independent non-inverting buffers, each with an open-drain output capable of sinking up to 32 mA. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, enabling safe mixed-voltage bus sharing.
It operates across 0.8 V–2.7 V VCC but is optimized for 1.65–1.95 V; input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), and output voltage range extends to VCC + 0.5 V, supporting 3.6-V tolerant I/O in mixed-mode signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V; fully functional down to sub-1-V, enabling ultra-low-power system integration |
| Max tpd | 2.5 ns at 1.8 V, CL = 15 pF; ensures timing-critical signal buffering in high-speed digital interfaces |
| IOL Drive | ±8 mA at 1.8 V; sufficient to drive standard CMOS loads and pull-down termination resistors |
| Ioff Support | Active during power-down; blocks current flow between powered and unpowered domains, critical for hot-swap and partial-power-down designs |
| IOH/IOZ | Open-drain output; requires external pull-up for logic high; enables wired-AND/wired-OR bus topologies |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM; meets industrial-grade robustness requirements without added protection circuitry |

Pinout & Package
SOT-23 (DBV) package - 6-pin, 1.45-mm maximum height, JEDEC MO-178 compliant, with pin 1 marked by index area and located in quadrant Q3 on tape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input; accepts 0.8–3.6 V logic signals, VIH/VIL scale with VCC |
| 2 | GND | Ground reference; must be connected directly to system ground plane for noise immunity |
| 3 | 1Y (Output) | Open-drain output of first buffer; requires external pull-up resistor to define high state |
| 4 | 2Y (Output) | Open-drain output of second buffer; electrically isolated from 1Y; supports independent wired-logic implementation |
| 5 | VCC | Supply rail; powers internal logic; supports 0.8–2.7 V; decoupling capacitor required within 1 cm |
| 6 | 2A (Input) | Second buffer input; identical electrical behavior to Pin 1; enables dual-channel level translation |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Dies-as-package construction reduces footprint and thermal resistance; eliminates wirebond parasitics for improved signal integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DBVR | Higher VCC min (1.65 V), lower drive (±24 mA @ 3.3 V), no sub-1-V operation | Optimized for 3.3-V systems; lacks 0.8-V functionality and NanoFree packaging | Select when operating strictly at ≥1.65 V and requiring broader industry familiarity |
| NC7SZ07P5X | Single-channel, SC-70-5 package, 3.6-V tolerant, 1.65–5.5 V VCC range | Requires two devices for dual-channel use; smaller footprint but no Ioff support | Choose for space-constrained single-buffer needs where partial-power-down is not required |
Compared with SN74LVC2G07DBVR and NC7SZ07P5X, the SN74AUC2G07DBVR uniquely combines sub-1-V operation, NanoFree packaging, and Ioff in a dual-channel SOT-23, making it optimal for next-generation ultra-low-power, hot-pluggable, and mixed-voltage embedded designs.

FAQ
What is the minimum supply voltage at which SN74AUC2G07DBVR remains fully functional?
The SN74AUC2G07DBVR is fully specified down to 0.8 V VCC and operates reliably across 0.8 V–2.7 V. At 0.8 V, it maintains valid logic thresholds (VIH = 0.52 V, VIL = 0.28 V) and delivers usable output drive, making SN74AUC2G07DBVR ideal for energy-harvesting and ultra-low-power applications where supply rails dip below 1 V.
Does SN74AUC2G07DBVR support hot-swapping between powered and unpowered systems?
Yes. SN74AUC2G07DBVR incorporates Ioff circuitry that disables outputs during power-down, preventing damaging current backflow when VCC = 0 V. This allows SN74AUC2G07DBVR to safely interface between active and inactive subsystems-critical for hot-pluggable modules, field-replaceable units, and partial-power-down architectures.
Can SN74AUC2G07DBVR drive standard 3.3-V logic inputs directly?
Yes. SN74AUC2G07DBVR is 3.6-V I/O tolerant: its inputs and outputs withstand up to 3.6 V regardless of VCC. When used with a 3.3-V pull-up, SN74AUC2G07DBVR's open-drain output can directly drive 3.3-V CMOS inputs without level-shifting components-provided the driven device recognizes VOL ≤ 0.6 V as logic low at 3.3 V.
What is the maximum sink current capability of SN74AUC2G07DBVR at 1.8 V?
At 1.8 V VCC, SN74AUC2G07DBVR guarantees ±8 mA output drive under standard conditions. Its absolute maximum sink current is 32 mA, but sustained operation above ±8 mA requires thermal validation. For robust 1.8-V bus driving, SN74AUC2G07DBVR delivers predictable performance with VOL ≤ 0.45 V at 8 mA, ensuring noise margin compliance.
Is SN74AUC2G07DBVR pin-compatible with other dual open-drain buffers in SOT-23 packages?
SN74AUC2G07DBVR uses standard SOT-23 (DBV) pinout: Pin 1 = 1A, Pin 2 = GND, Pin 3 = 1Y, Pin 4 = 2Y, Pin 5 = VCC, Pin 6 = 2A. This matches industry-standard dual buffer layouts (e.g., SN74LVC2G07DBVR, 74AHC1G07 variants), enabling drop-in replacement where voltage and drive requirements align-though Ioff and sub-1-V operation are unique to SN74AUC2G07DBVR.
